Item cannot be expanded
Microsoft Excel has reached the maximum number of rows or
columns for this worksheet. The number of rows and columns is limited in Microsoft Excel. Expanding the current item is not possible because it
would shift rows or columns beyond this worksheet limit. Microsoft Excel cannot shift nonblank cells off the worksheet.
Manually move items so that the row or column item can expand without reaching the limit, or move your Exploration View, list, or report to another worksheet. Or, you can move the data to a new location and try again.
